OE-HB-62.5型小负荷布氏硬度计采用精密机械技术和光电技术的新型维氏硬度计。该机采用微机控制，通过软件能调节测量光源的强弱，并能试验力保持时间，以LEG显示。该机采用独特的测量转换和测微目镜一次测量读数机构，使用方便，测量精度高。
硬度计配可选摄影装置，能对所测压痕和材料金相组织进行拍摄，适用于铸铁、有色金属及其合金，各种退火调质处理后的钢材，特别是对较软的金属如纯铝，铅，锡测量的硬度较正确，是科研机构、企业及质检部门进行研究和检测的理想硬度测试仪器。
Model HB-62.5 Low Load Hardness Tester is a new hi-tech product integrating
precision mechamical and photoelectrical technologies.
The following highlight key features and functions of this tester:
--Micro computer control;
--Adjustment of lightng source via soft keys;
--Adjustment of pressure holding time and LED display;
--Unigue measurement conversion device and unique micro eyepiece one-time
measurement;
--Camera for indention photographiny and metallography.
The tester can take pictuture of impress and metallo of the material
with a camera. It can measure castiron, no-ferrous, alloy and anealed
steel, it specially designed for testing soft metal such as alumimium,
tin etc. For research institutes, factories labs and QC departments,
this is an ideal hardness testing instrument for research or measuring
purposes.
